How to display Tree2 node description/content in a separate frame

Prerequisites:
- Some knowledge of JSP/JSF
- Some knowledge of MyFaces Tree2
- Familiar with HTML/Javascript

Solution:
1)Define TreeView and NodeDetails frameset
2)Define TreeView JSP
3)Define NodeDetails JSP
4)Use HTML <body>.onload event to update NodeDetails frame's content

Other notes:
- <body>.onload is a HTML/Javascript clientside event, implies that a node has been selected
- NodeDetails JSP can handle the case where no node selected i.e. first time the frameset loaded
- both frames shares the same session, and have access to the same backend bean (e.g. treebacker)

Code sample:
1)Separate Tree and NodeDetails views into separate frames e.g.
   <frameset cols="50%,50%" border=0 framespacing=0>
     <frame src="result-folders.faces;jsessionid=<%=jsid%>"
          name="TreeView" scrolling="auto">
     <frame src="folder-details.faces;jsessionid=<%=jsid%>"
            name="NodeDetails" scrolling="auto">
   </frameset>


2)Define Tree view in TreeView frame e.g. result-folders.jsp
    <t:tree2 id="serverTree"
          value="#{StatusTreeHandler.treeModel.treeData}"
          var="node" varNodeToggler="t" clientSideToggle="false"
          showRootNode="false">
       <f:facet name="folder">
          <h:panelGroup>
            <t:graphicImage value="images/yellow-folder-open.png"
                rendered="#{t.nodeExpanded}" border="0"/>
            <t:graphicImage value="images/yellow-folder-closed.png"
                 rendered="#{!t.nodeExpanded}" border="0"/>
            <h:commandLink
                 action="nodeClicked"
                 styleClass="#{t.nodeSelected ? 'documentSelected':'document'}"
                 actionListener="#{StatusTreeHandler.processAction}"
                 value="#{node.description}" immediate="true">
            </h:commandLink>
          </h:panelGroup>
       </f:facet>
       <f:facet name="leaf">
          <h:panelGroup>
            <t:graphicImage value="images/document.png" border="0"/>
            <h:outputText value="*" rendered="#{t.nodeSelected}"/>
            <h:commandLink action="nodeClicked"
                 styleClass="#{t.nodeSelected ? 'documentSelected':'document'}"
                 actionListener="#{StatusTreeHandler.processAction}"
                 value="#{node.description}" immediate="true">
            </h:commandLink>

          </h:panelGroup>
       </f:facet>
3)Define Node Details View in NodeDetails frame e.g. folder-details.jsp
     <h:panelGroup>
       <h:panelGroup>
         <h:outputText style="font-size: 12pt; font-wight: bold; text-align: top"
                       value=<%=label%>/>
         <h:outputText rendered="#{StatusTreeHandler.folderSelected}"
                       value="#{StatusTreeHandler.selectedFolder}"/>
       </h:panelGroup>
       <h:dataTable id="resultList" width="100%"
          columnClasses="col1, col2"
          rowClasses="row1, row2"
          rendered="#{StatusTreeHandler.resultSelected}"
          value="#{StatusTreeHandler.results}"
          var="result"
          border="1">
         <h:column>
           <f:facet name="header">
             <h:outputText style="font-size: 12pt; font-wight: bold" value="Name"/>
           </f:facet>
           <h:outputText value="#{result.name}"/>
         </h:column>
         <h:column>
           <f:facet name="header">
             <h:outputText style="font-size: 12pt; font-wight: bold"
                value="Value"/>
           </f:facet>
           <h:outputText value="#{result.value}"/>
         </h:column>
       </h:dataTable>
     </h:panelGroup>
